Diabellstar Deck #772272 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Fusion/Link
• Format: ocg

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Link and Fusion boss monsters from the Extra Deck (Infernoid Tierra, Infernoid Flood, Promethean Princess, Amblowhale, Underworld Goddess) once a Infernoid starter is live; Diabellstar and Azamina board pressure with battle damage and direct-attack text, if the Infernoid engine stalls
• Turn 1 (going first): Open a starter such as Infernoid Antra, Pirmais or Harmadik, banish a 1-cost Infernoid from hand or GY to Special Summon it, then use Void Feast or Void Vanishment to reach Level 8 and summon a boss. Illegal copy counts make this line unverifiable as built.
• Turn 2 (going second): Rely on Infernoid Flood and Ultimate Sky negation, then a Link or Fusion boss. Evidence for this plan is thin: there are no hand traps and no recorded second-player boards.
• Recovery: Recurse through Void Reignition, Void Breach, Deception of the Sinful Spoils and WANTED: Seeker from the GY. Recovery is text-supported only, not observed.
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 adaptation cannot be evaluated.

Why it scores here

The deck is scored as a system, not as an average of its cards. The Infernoid core (Antra, Pirmais, Harmadik, Piaty, Attondel) is 3-copy heavy, so a starter is live in an opening hand about 23% of the time on the play (Inferred, from the hypergeometric draw table). The starters need banished Infernoid fodder from hand or GY, which is why the engine is slower than its card count suggests. Interaction is real (12 negation-text and 25 removal-text cards, Infernoid Flood as a Quick Effect negate), and the Link and Fusion closers (Tierra 3400 ATK, Flood 3000 ATK, Goddess 3000 ATK) give it reach. Two of the Extra Deck slots (Azamina Ilia Silvia and Reprodocus) are Forbidden, and Monster Gate and Reasoning are each over their Limited copy count, so the list is illegal and the final score is capped. Popularity did not earn points: the archetype is well used in usage statistics, but that confirms only that the list is real, not that it is strong.

Dimension scores

How the score was computed

Strategy profile: Combo primary; the Midrange secondary is folded into the profile weights. Structural ≈ 42, Going First ≈ 40, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-12). Final formula: Theoretical only (illegal deck): uncapped = 0.80*Structural(42) + 0.20*TournamentReliability(30) + banlist modifier(-12) = 28; illegal cap applied -> 20. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong Link and Fusion closers with 3000+ ATK and negation text
• Multiple engines (Infernoid, Diabellstar, Azamina) reduce single-starter dependence
• Good removal density (25 removal-text cards)

Weaknesses

• Illegal list: 3 Forbidden cards and 2 over-limit Limited cards
• No side deck
• Starters need banished fodder, so the engine is slow to go live
• No hand traps, so no going-second disruption

Critical choke points

• A live Infernoid starter needs 1-3 banished Infernoid monsters from hand or GY
• Two Forbidden Extra Deck cards occupy Extra slots that cannot be legally filled

Recommended changes

Evidence & confidence

• Verified: Illegal status: Forbidden cards and over-limit copies present in the OCG list; Main Deck 60, Extra Deck 15, Side Deck 0 (within OCG size rules); Card text for the 3-copy Infernoid core and Link closers (from evidence)
• Observed: Usage statistics show Diabellstar and Azamina as core archetype cards (inclusion 52-73%)
• Inferred: Starter opening-hand odds (0.233 on the play) from hypergeometric draws; Engine redundancy and interaction quality from card text; Going-second plan quality (no hand traps, no recorded boards)
• Provisional: Meta Power and matchup fit (no dated metagame sample, no tournament link); Side deck adaptability (no side deck registered)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot records are absent No win-rate telemetry for going-first, going-second, matchups, or brick rate Meta Power is provisional without a dated metagame sample No side deck registered
